I am using RoboHelp 9 and was performing my search on published WebHelp.
In the Help there is a topic named "Port and Path Connection States" which references a status of "port not started".
When I search for "port not started" (without quotes), I get this message: "The words you typed is not a valid expression.".
I thought this search would be treated as an OR search, and I would get results for all topics that contained the word "port" or "not" or "started", but instead the expression is not valid. Can anyone tell me why?
